/*
 * Design System — Japanese-inspired minimal aesthetic
 *
 * Font:     Inter (Google Fonts) — clean, geometric sans-serif with
 *           precise letterforms. Loads weights 300, 400, 600.
 *
 * Palette:  Near-black text (#1a1a1a) on warm off-white (#fafaf9).
 *           Avoids pure black/white for a softer, more natural contrast.
 *           Buttons use Pico's default primary blue.
 *
 * Sizing:   Base font 15px with light weight (300) for body copy.
 *           Headings use weight 400-600; size provides hierarchy.
 *           Generous whitespace throughout.
 *
 * Layout:   Container max-width 720px. Responsive vertical padding
 *           (2rem mobile, 6rem desktop). Inline padding at all widths.
